USA Today has put together a very partial list of Democrats who made the same promise about Obamacare as Obama:

Sen. Patty Murray of Washington, June 10, 2009: We here in the Senate are working on legislation that will protect people's choice of doctors, will protect their choice of hospitals, will protect their choice of insurance plan. If you like what you have today, that will be what you have when this legislation is passed. (Source: Remarks on the Senate floor.)

Sen. Harry Reid of Nevada, July 28, 2009: The reform we are pursuing … not only means making sure you can keep your family's doctor or keep your health care plan if you like it but also that you can afford to do so. (Source: Remarks on the Senate floor.)

Sen. Dick Durbin of Illinois, July 30, 2009: Many people say: I like my health insurance right now. I don't want to change. I don't want to go into Medicare or Medicaid. I like what I have. Would you please leave people alone. The answer is yes. In fact, we guarantee it. We are going to put in any legislation considered by the House and Senate the protection of you, as an individual, to keep the health insurance you have, if that is what you want. What we are trying to create are voluntary choices and opportunities. (Source: Remarks on the Senate floor.)

President Obama, Aug. 15, 2009: At the same time — I just want to be completely clear about this; I keep on saying this but somehow folks aren't listening — if you like your health care plan, you keep your health care plan. Nobody is going to force you to leave your health care plan. (Source: Remarks from town hall on health care.)

President Obama, March 25, 2010: From this day forward, all of the cynics, all the naysayers — they're going to have to confront the reality of what this reform is and what it isn't. They'll have to finally acknowledge this isn't a government takeover of our health care system. They'll see that if Americans like their doctor, they'll be keeping their doctor. You like your plan? You'll be keeping your plan. No one is taking that away from you. (Source: Remarks in Iowa City, Iowa.)

Sen. Max Baucus of Montana, Sept. 29, 2010: From the beginning, the law has been about preserving what is good about American health care. That is why one of the central promises of health care reform has been and is: If you like what you have, you can keep it. That is critically important. If a person has a plan,and he or she likes it, he or she can keep it. (Source: Remarks on the Senate floor.)

Sen. Carl Levin of Michigan, April 6, 2012: This bill will help make health insurance more secure for those who already have it and make coverage available for millions of uninsured Americans. And it is important to remember that for those who already have health insurance, the law allows you to keep your existing plan. (Source: Press release.)

President Obama, June 28, 2012: First, if you're one of the more than 250 million Americans who already have health insurance, you will keep your health insurance — this law will only make it more secure and more affordable. (Source: Remarks on Supreme Court ruling on the Affordable Care Act.)

Sen. Jeff Merkley of Oregon, web page accessed Nov. 11, 2013: If you like your current health insurance, you will be able to keep it. And you will be able to continue seeing your current doctor. Health care reform would simply give you the choice to change insurance providers if you so choose. (Source: Q & A webpage.)

White House web page, accessed Nov. 11, 2013: If you like your plan you can keep it and you don't have to change a thing due to the health care law. The President addressed concerns from Americans who have received letters of policy cancellations or changes from their insurance companies in an interview with NBC News, watch the video or read a transcript.
